Then, when the ETC card attaching / detaching mechanism is activated, the ETC card 5 is automatically moved (attached) from a predetermined insertion position to a proper attachment position, and an eject button (not shown) is operated. Then, when the ETC card attaching / detaching mechanism is operated, the ETC card 5 is automatically moved (discharged) from the normal mounting position to the predetermined extraction position.
[0016]
A keyboard 8 in which a plurality of (in this case, four) mechanical keys are arranged is disposed on the front portion of the lid 7, and a liquid crystal display 9 (display means in the present invention) is disposed. Has been. In this case, as mechanical keys, for example, a “power” key for turning on power, an “open” key for opening the lid 7, and a “close” key for closing the lid 7 are used. Etc. On the liquid crystal display 9, touch type numeric keys and character keys are displayed on the display screen as touch keys. And the vehicle-mounted terminal 1 comprised in this way can be attached to the din 11 in the vehicle interior 10, as shown in FIG.
[0017]
FIG. 4 shows the electrical configuration of the above-described in-vehicle terminal 1 as a functional block diagram. The control circuit 12 (control means in the present invention) is configured mainly with a microcomputer and has a function of controlling the overall operation of the in-vehicle terminal 1. When any mechanical key is operated, the keyboard 8 outputs an operation signal representing the operated content to the control circuit 12. When a display command signal is input from the control circuit 12, the liquid crystal display 9 displays display information based on the input display command signal on the display screen and displays touch keys on the display screen. When any of the touch keys is operated, an operation signal indicating the operated content is output to the control circuit 12. The drive mechanism 13 moves the lid 7. When a drive signal is input from the control circuit 12, the drive mechanism 13 moves the lid 7 based on the input drive signal.
[0018]
The CD slot 4 outputs a mounting signal to the control circuit 12 when the CD 3 is mounted. The control circuit 12 receives the mounting signal from the CD slot 4 so that the CD 3 is used for the CD. It is possible to recognize that it is installed in the slot 4. Further, when the ETC card 5 is inserted, the ETC card slot 6 outputs a mounting signal to the control circuit 12, and the control circuit 12 receives the mounting signal from the ETC card slot 6, It is possible to recognize that the ETC card 5 is installed in the ETC card slot 6.
[0019]
Next, the operation of the above configuration will be described with reference to FIGS. Here, the description will be made on the assumption that the lid 7 is stationary at the normal position.
The control circuit 12 detects that the “open” key is operated on the keyboard 8 based on the operation signal input from the keyboard 8, and determines that the operation for causing the lid 7 to perform the opening operation has been performed. If detected ("YES" in step S1), it is determined whether or not the ETC card 5 is installed in the ETC card slot 6 by determining whether or not an installation signal is input from the ETC card slot 6. Determine (step S2).
[0020]
When the control circuit 12 determines that the ETC card slot 6 receives a mounting signal and the ETC card 5 is mounted in the ETC card slot 6 ("YES" in step S2), authentication setting is performed. Whether or not is valid is determined (step S3). In this case, the authentication setting is a determination as to whether authentication is required when the ETC card 5 is removed from the ETC card slot 6, and the user sets the authentication setting to be valid in advance. When the ETC card 5 is removed, authentication can be required. On the other hand, by previously setting the authentication setting to invalid, authentication can be made unnecessary when the ETC card 5 is removed.
[0021]
When the control circuit 12 determines that the authentication setting is valid (“YES” in step S3), the control circuit 12 outputs the drive signal to the drive mechanism 13, thereby moving the lid 7 from the normal position to the first movable position. (Step S4). As a result, the slot for the CD slot 4 is opened, so that the user can insert the CD 3 into the CD slot 4 or remove the CD 3 from the CD slot 4. At this time, the lid 7 moves so that the display screen of the liquid crystal display 9 faces upward as described in FIG.
[0022]
Next, the control circuit 12 outputs a display command signal to the liquid crystal display 9, and as shown in FIG. 6, for example, the liquid crystal display 9 displays a display guidance that prompts the user to enter a password “Please enter the password”. Are displayed on the display screen, and touch type numeric keys “0” to “9” for inputting the personal identification number are displayed on the display screen of the liquid crystal display 9 (step S5). “0” is set (step S6). Here, the user operates a touch-type numeric key, and inputs a personal identification number composed of, for example, a 4-digit number.
[0023]
The control circuit 12 detects that a touch-type numeric key has been operated on the liquid crystal display 9 based on an operation signal input from the liquid crystal display 9, and an operation for inputting a password is performed. If this is detected ("YES" in step S7), authentication is performed by comparing the entered password with a preset regular password (step S8). In this case, the regular personal identification number may be a number unique to the terminal or may be a variable number arbitrarily set by the user.
[0024]
When the control circuit 12 determines that the input personal identification number matches the preset regular personal identification number and the authentication is correct (“YES” in step S9), the drive signal Is output to the drive mechanism 13 to move the lid 7 from the first movable position to the second movable position (step S10). As a result, the slot for the ETC card slot 6 is opened, so that the user can insert the ETC card 5 into the ETC card slot 6 or remove the ETC card 5 from the ETC card slot 6. Can do.
[0025]
On the other hand, when the control circuit 12 determines that the input personal identification number does not match the preset regular personal identification number and the authentication is rejected ("NO" in step S9). The counter n is incremented (step S11), and the incremented counter n is compared with a specified value N (for example, N = “3”) (step S12). In this case, the specified value N is a value that limits the number of times the PIN code is input, and may be a value unique to the terminal or may be a variable value that is arbitrarily set by the user.
[0026]
If the control circuit 12 determines that the incremented counter n is less than the specified value N (“YES” in step S12), the control circuit 12 returns to step S7 described above. On the other hand, when the control circuit 12 determines that the incremented counter n is greater than or equal to the specified value N (“NO” in step S12), the control circuit 12 moves the lid 7 from the first movable position to the second movable position. The process is finished without.
[0027]
The control circuit 12 determines that the ETC card 5 is not inserted in the ETC card slot 6 (“NO” in step S2), or determines that the authentication setting is invalid (in step S3). "NO"), by outputting a drive signal to the drive mechanism 13, the lid 7 is moved from the normal position to the second movable position without being stopped at the first movable position (step S13).
[0028]
By the way, when displaying touch type numeric keys “0” to “9” on the display screen of the liquid crystal display 9 for the user to input the password, as shown in FIG. The configuration may be such that the “9” numeric keys are displayed according to a random arrangement. Further, instead of the numeric keys “0” to “9”, for example, characters (alphabet) keys “A” to “Z” may be displayed and authenticated by inputting the characters.
[0029]
As described above, according to the present embodiment, in the in-vehicle terminal 1, when the lid 7 is moved to the first movable position, the CD 3 can be attached to and detached from the CD slot 4, and at the same time, the ETC card 5 On the other hand, when the lid 7 is moved to the second movable position on the condition that the authentication is positive, the ETC card 5 cannot be attached to or detached from the ETC card slot 6. 6 is configured to be detachable with respect to the vehicle, so that a plurality of recording media such as the CD3 and the ETC card 5 can be detachable at the same time, so that the space in the passenger compartment 10 can be used effectively. The safety can be improved by making the ETC card 5 removable on the condition that the authentication is positive and avoiding unauthorized removal of the ETC card 5 in advance. Kill.
[0030]
Further, in this case, a simple structure in which the lid 7 opens and closes can restrict the attachment / detachment of the CD 3 and the ETC card 5, and the lid 7 can be attached to the attachment / detachment opening 4 a of the CD slot 4 or the ETC card slot 6. By closing the detachable opening 6a, it is possible to prevent dust from entering the CD slot 4 and the ETC card slot 6.
[0031]
In this case, since the numeric keys are displayed on the display screen according to a random arrangement, the operation position on the display screen is the same every time when the user inputs a regular numeric string corresponding to the password. For example, the personal identification number is not illegally read by another person based on an operation mark (such as a fingerprint) attached on the display screen, and safety can be further improved.
[0032]
Further, in this case, it is configured so that it can be attached to the din 11 in the passenger compartment 10, and the display screen of the liquid crystal display 9 faces upward when the lid 7 is moved to the first movable position. The numeric keys displayed on the display screen can be operated looking down, and the operability can be improved.
[0033]
Further, in this case, the CD slot 4 in which the CD 3 is mounted is arranged on the upper side, and the ETC card slot 6 in which the ETC card 5 is inserted is arranged on the lower side. The CD slot 4 that does not require authentication when attaching and detaching is arranged on the upper side, and the ETC card slot 6 that requires authentication when attaching and detaching the ETC card 5 is arranged on the lower side. Can be increased.
